答案（中文）
石油类UVCB物质的生产工艺描述应包含以下信息：获得石油流的原料：对于直馏常压馏分油和常压渣油，原料可以是原油。对于其他石油物质，原料往往是中间体原料，应说明炼油工艺所针对的石油流名称。例如：对于重整油馏分，原料可以是原油常压蒸馏后的重石脑油馏分；对于减压馏分油，原料可以是原油常压蒸馏后的渣油；对于基础油，原料通常是减压馏分油；对于裂解工艺得到的石脑油馏分，原料可以是减压馏分油或重质常压柴油；对于进口柴油，原料可以是原油衍生的各种石油流，需尽可能具体说明。应用于源材料的炼油工艺：这可能包括混合工艺（按规范混合），应提供国际标准（如 EN228、EN590 等）描述的规范。例如：对于轻质重整油馏分，炼油工艺包括原油分馏、石脑油加氢处理、催化重整和重整油分馏。描述最终馏分的收集方式（常压蒸馏、馏出物/残渣馏分；减压蒸馏、馏出物/残渣馏分；溶剂萃取、萃取物/萃余相等）。注册物质的规范：需要提供沸点范围和碳数范围的典型测值。如果物流在其 EC 描述中由其他参数（如粘度）定义，则也需要提供这些参数。无需提供炼油厂特定的工艺参数（如精炼温度、催化剂、溶剂等）。所有与生产工艺描述相关的信息均应包含在IUCLID第1.2节的“描述”字段中。无法以自由文本形式提供的生产工艺信息（例如图表、示意图等）应以文件形式提供，并按照问答1199中的说明附加。
Answer (EN)
The manufacturing process description for petroleum UVCB substances should contain the following information: Source material from which the petroleum stream is obtained: For straight-run atmospheric distillates and atmospheric residue, the source material could be crude oil. For other petroleum substances, the source materials are often intermediate stocks and the name of the petroleum stream(s) to which the refinery process is applied should be specified. For example: for reformate fractions, the source material could be heavy naphtha fraction from the atmospheric distillation of crude oil; for vacuum distillates, the source material could be the residue from the atmospheric distillation of crude oil; for base oils, the source material for is normally a vacuum distillate; for naphtha fraction as a result of cracking process, the source material could be a vacuum distillate or heavy atmospheric gas oil; for imported gas oil, the source material could be various petroleum streams derived from crude oil, which need to be specified as far as possible. Refinery process(es) applied to the source material(s): This may include blending processes (blending to specification), for which specification described by an international standard (e.g. EN228, EN590, etc.) should be provided. For example: for a light reformate fraction, the refinery processes include crude oil fractionation, naphtha hydrotreatment, catalytic reforming and reformate fractionation. Description as to how the final fraction is collected (atmospheric distillation, distillate/residue fraction; vacuum distillation, distillate/residue fraction; solvent extraction, extract/raffinate phase, etc.). Specification of the registered substance: Measured typical values of boiling point range and carbon number range need to be provided. If a stream is defined in its EC description by other parameters (e.g. viscosity) they also need to be provided. The refinery-specific process parameters (e.g. refining temperature, catalysts, solvents, etc.) do not need to be provided. All relevant information on the manufacturing process description should be included in the “Description” field in section 1.2 of IUCLID. Information on the manufacturing process that cannot be provided as free text (graphs, schemes, etc.) should be provided in a document and attached as instructed in Q&A 1199.
